Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597350, here are decompositions:

13 + 31597337 = 31597350
67 + 31597283 = 31597350
89 + 31597261 = 31597350
97 + 31597253 = 31597350
107 + 31597243 = 31597350
137 + 31597213 = 31597350
151 + 31597199 = 31597350
173 + 31597177 = 31597350

Showing the first eight; more decompositions exist.
